Was playing with the "secret" menus and on one of the hidden screens, pressed clear, thinking it would clear only the entries represented on the screen (there was no indication that it was my waypoint memory).. Nonetheless, I lost all of my NAV entries.. Oh well, I just have to remember to mark them next time I visit those points again...

But I wish I wasn't so button happy haha...

Let it be a warning to all you curious cats out there.. DON'T BE AN idiot (like me) and hit the CLEAR button.. :^)
